"Wnt regulation of beta-catenin degradation is essential for development and carcinogenesis. beta-catenin degradation is initiated upon amino-terminal serine/threonine phosphorylation, which is believed to be performed by glycogen synthase kinase-3 (GSK-3) in complex with tumor suppressor proteins Axin and adnomatous polyposis coli (APC)."

"NEK2 silencing reduced the phosphorylation of beta-catenin at Ser33 and Ser37, but did not decrease the level of total beta-catenin.|NEK2 slightly decreased the level of total beta-catenin (XREF_FIG)."

"As shown in Fig. 1 B, PKCalpha readily phosphorylated Ser33 and Ser37 / Thr41 on full-length beta-catenin (beta-catenin 1 - 781) and CTD deletion mutant (beta-catenin 1-682).|To examine the effect of the armadillo repeats 1-5 on PKCalpha mediated beta-catenin degradation, DNA constructs expressing beta-catenin 1 - 781 and beta-catenin deletion mutants (beta-catenin 1-422 and beta-catenin 1-138) were transfected into HEK293 cells, followed by treatment with increasing concentrations of A23187 and CGK062, which are known activators of PKCalpha."

"This leads to the inactivation and release of glycogen synthase kinase 3beta from its complex with axin, thereby relieving the inhibitory phosphorylation of beta-catenin and activating its signaling pathway."

"GSK3β regulates β-catenin stability by phosphorylating serine and threonine residues (Ser33/37 and Thr41) important for targeting β-catenin for ubiquitin-dependent proteasomal degradation"

"Beta-catenin phosphorylation in vivo is sequentially carried out by two distinct kinases, ckialfa and gsk-3. Ckialfa phosphorylation of s45 proceeds and is required for subsequent gsk-3 phosphorylation of t41, s37, and s33 one key substrate of gsk3 is the transcriptional co-activator beta catenin, whichis inactivated by gsk3 mediated phosphorylation and targeted for proteasomal degradation in unstimulated cells."

"DISC1 inhibits GSK3beta activity through direct physical interaction, which reduces beta-catenin phosphorylation and stabilizes beta-catenin."
